Intraoperative monitoring of neuromuscular function with soft, tissue-mounted wireless devices

Abstract

The provided systems, methods and devices describe lightweight, wireless tissue monitoring devices that are capable of establishing conformal contact due to the flexibility or bendability of the device. The described systems and devices are useful, for example, for skin-mounted intraoperative monitoring of nerve-muscle activity. The present systems and methods are versatile and may be used for a variety of tissues (e.g. skin, organs, muscles, nerves, etc.) to measure a variety of different parameterps (e.g. electric signals, electric potentials, electromyography, movement, vibration, acoustic signals, response to various stimuli, etc.).

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of and priority to U.S. Provisional Patent Application No. 62 / 634,440, filed Feb. 23, 2018, which is hereby incorporated by reference in its entirety to the extent not inconsistent herewith.BACKGROUND OF INVENTION[0002]Surgical nerve damage where inadvertent damage is caused to nerves during surgery is a significant concern to medical professionals as it can lead to significant patient pain and, in some cases, loss of motor function. Intraoperative techniques have been developed to monitor nerve activity during surgery in attempts to avoid or reduce nerve damage. However, many conventional intraoperative techniques require that electrode leads be percutaneously placed inside of a patients muscle tissue and wired to a bench-top console, which causes patient discomfort and bleeding and requires additional surgery time and trained medical personnel, which increases costs. The increased cost of intraoperati...

Problems solved by technology

Surgical nerve damage where inadvertent damage is caused to nerves during surgery is a significant concern to medical professionals as it can lead to significant patient pain and, in some cases, loss of motor function.

However, many conventional intraoperative techniques require that electrode leads be percutaneously placed inside of a patients muscle tissue and wired to a bench-top console, which causes patient discomfort and bleeding and requires additional surgery time and trained medical personnel, which increases costs.

The increased cost of intraoperative monitoring has e
